It used to be the case up until about 5-6 years ago. Then NSW changed the penalties, or some such thing. The ACT decided not to recognise them, so it stopped. It meant that someone disqualified from driving in NSW could, quite legally, drive in the ACT and elsewhere in Australia on a valid licence.

It’s “meant” to have been the case for quite some time now (many years). And the police will certainly tell you that (since as far as they’re concerned, that is indeed the case). The reality is that the administration of it doesn’t always keep up with what’s “meant” to happen.
I’m not suggesting you should rely on it not happening, and I’m certainly not advocating any kind of driving that would incur you points – quite the opposite. I’m just saying don’t be too surprised if points incurred in NSW still slip through the cracks.

Was just out around the Cowra / Bathurst area over the long weekend and saw regular police patrols with mobile radars fitted, both on open roads and within towns. Phew what a relief to get back across the border into ACT this afternoon and onto Gunghalin Drive / Tuggie Pkwy where you know you don’t need to worry about silly things like speed limits. Home sweet home.
